Is the formatted HTML executed?

No. Result text is displayed in a read-only editor. Scripts in the input are not run.

Does this fix invalid HTML?

No. It beautifies what you paste. Unclosed tags may still look uneven after format.

Is my markup uploaded?

No. Formatting runs entirely in your browser.

Will inline or blocks be reformatted?

The HTML beautifier indents embedded blocks as part of the document tree. It does not run the JavaScript or CSS formatters inside them — use those tools for language-specific layout.

Can I format HTML fragments without ?

Yes. Partial snippets such as a subtree or table markup can be pasted. The formatter adds indentation relative to what you provide, not a full document wrapper.
